Background.Despite a proliferation of phlebotomy devices with engineered sharps injury protection (ESIP), the impact of various winged device designs on blood splatter occurring during venipuncture procedures has not been explored.Objectives.To evaluate the potential for blood splatter of 6 designs of winged phlebotomy devices.Design.A laboratory-based device evaluation without human subjects, using a simulated patient venous system.Methods.We evaluated 18 winged phlebotomy devices of 6 device designs by Terumo, BD Vacutainer (2 designs), Greiner, Smith Medical, and Kendall (designated A-F, respectively). Scientific filters were positioned around the devices and weighed before and after venipuncture was performed. Visible blood on filters, exam gloves, and devices and measurable blood splatter were the primary units of analysis.Results.The percentages of devices and gloves with visible blood on them and filters with measurable blood splatter ranged from 0% to 20%. There was a statistically significant association between device design and visible blood on devices (P< .0001) and between device design and filters with measurable blood splatter (P< .0001), but not between device design and visible blood on gloves. A wide range of associations were demonstrated between device design and visible blood on gloves or devices and incidence of blood splatter.Conclusions.The results of this evaluation suggest that winged phlebotomy devices with ESIP may produce blood splatter during venipuncture. Reinforcing the importance of eye protection and developing a methodology to assess ocular exposure to blood splatter are major implications for healthcare personnel who use these devices. Future studies should focus on evaluating different designs of intravascular devices (intravenous catheters, other phlebotomy devices) for blood splatter.

From PDAs to cell phones to MP3 players, handheld electronic devices are ubiquitous. Human factors engineers and designers have a need to remain informed about advances in research on user interface design for this class of devices. This review provides human factors research summaries and research-based guidelines for the design of handheld devices. The major topics include anthropometry (fitting the device to the hand), input (types of device control and methods for data entry), output (display design), interaction design (one-handed use, scrolling, menu design, image manipulation, and using the mobile Web), and data sharing (among users, devices, and networks). Thus, this review covers the key aspects of the design of handheld devices, from the design of the physical form of the device through its hardware and software, including its behavior in networks.

<abstract> <p>Camera devices are being deployed everywhere. Cities, enterprises, and more and more smart homes are using camera devices. Fine-grained identification of devices brings an in-depth understanding of the characteristics of these devices. Identifying the device type helps secure the device safe. But, existing device identification methods have difficulty in distinguishing fine-grained types of devices. To address this challenge, we propose a fine-grained identification method based on the camera deviceso inherent features. First, feature selection is based on the coverage and differences of the inherent features type. Second, the features are classified according to their representation. A design feature similarity calculation strategy (FSCS) for each type of feature is established. Then the feature weights are determined based on feature entropy. Finally, we present a device similarity model based on the FSCS and feature weights. And we use this model to identify the fine-grained type of a target device. We have evaluated our method on Dahua and Hikvision camera devices. The experimental results show that we can identify the deviceos fine-grained type when some inherent feature values are missing. Even when the inherent feature pmissing rateq is 50%, the average accuracy still exceeds 80%.</p> </abstract>

As designers of mobile/media-rich devices continue to incorporate more features/functionality, the evolution of interfaces will become more complex. Meanwhile, users cognitive models must be aligned with new device capabilities and corresponding physical affordances. In this paper, the authors argue that based on HCI design theory, users approach objects by building mental models starting with physical appearance. Findings suggest that users who embrace a device’s multifunctionality are prevented from taking full advantage of an array of features due to an apparent cognitive constraint caused by a lack of physical controls. The authors submit that this problem stems from established mental models and past associated behaviors of both mobile and non-mobile interactive devices. In conclusion, users expressed a preference for immediate access and use of certain physical device controls within a multi-tasking environment, suggesting that as mobile computing becomes more prevalent, physical affordances in multifunctional devices may remain or increase in importance.

The objective of this systematic review is to analyze types of needle-free connectors and open systems and their effects on central line–associated bloodstream infection rates and other adverse outcomes through a research protocol consistent with the Preferred Reporting Items for Systematic Reviews’ recommendations. MEDLINE and Cochrane databases of systematic reviews were searched for relevant comparative studies published from January 2000 to September 2017. Eighteen studies compared central line–associated bloodstream infection (according to the Centers for Disease Control and Prevention/National Healthcare Safety Network definition), internal microbial contamination, occlusions, phlebitis, and other outcomes associated with needle-free connectors with a positive displacement device, negative displacement device, neutral displacement device, or three-way stopcock. Ten studies reported central line–associated bloodstream infection rates, which were lower with positive displacement devices versus negative displacement devices/neutral displacement devices (one study) and with negative displacement devices versus three-way stopcocks (three studies), but varied with different positive displacement device and negative displacement device/neutral displacement device designs (four studies). Seven studies reported internal microbial contamination rates, which were higher with three-way stopcocks versus negative displacement devices (two studies) and positive displacement devices (two studies), lower when positive displacement devices were used versus neutral displacement devices (one study), and varied with different types of negative displacement device (one study). Central line–associated bloodstream infection rates and most other outcomes analyzed were statistically significantly higher with three-way stopcocks (open devices) versus positive displacement device, negative displacement devices, and neutral displacement devices, but varied among closed device designs.

Abstract As the physical size of semiconductor devices continues to be aggressively scaled down, feedback field-effect transistors (FBFET) with a positive feedback mechanism among a few promising steep switching devices have received attention as next-generation switching devices. Conventional FBFETs have been studied to explore their device performance. However, this has been restricted to the case of single FBFET; basic circuit designs with FBFETs have not been investigated extensively. In this work, we propose an inverter circuit design with silicon-on-insulator (SOI) FBFETs; we verified this inverter design with mixed-mode technology computer-aided design simulation. The basic principles and mechanisms for designing FBFET inverter circuits are explained because their configuration is different from conventional inverters. In addition, the device parameters necessary to optimize circuit construction are introduced for logic device applications.

This paper proposes a method to ensure compatibility between physical devices for implementing a service design. The method supports the relaxation of strict implementation. It allows a set of compatible devices to be implemented instead of specifying specific devices in the service design. This paper’s main contribution is the formalization of device constraints using the device’s attributes and a method to check the compatibility between devices. The method’s characteristic is that a service designer can decide the level of strictness and abstractness of the design by adjusting the compatibility rate. We show the feasibility of the proposed method to achieve the goal of “Design Once, Provide Anywhere” with an application example. We also evaluated the quality of service of the implemented IoT service in a different environment using a platform called Elgar.

The performance of nanoelectronic and molecular electronic devices relies strongly on the employed functional units and their addressability, which is often a matter of appropriate interfaces and device design. Here, we compare two promising designs to build solid-state electronic devices utilizing the same functional unit. Optically addressable Ru-terpyridine complexes were incorporated in supramolecular wires or employed as ligands of gold nanoparticles and contacted by nanoelectrodes. The resulting small-area nanodevices were thoroughly electrically characterized as a function of temperature and light exposure. Differences in the resulting device conductance could be attributed to the device design and the respective transport mechanism, that is, thermally activated hopping conduction in the case of Ru-terpyridine wire devices or sequential tunneling in nanoparticle-based devices. Furthermore, the conductance switching of nanoparticle-based devices upon 530 nm irradiation was attributed to plasmon-induced metal-to-ligand charge transfer in the Ru-terpyridine complexes used as switching ligands. Finally, our results reveal a superior device performance of nanoparticle-based devices compared to molecular wire devices based on Ru-terpyridine complexes as functional units.

There have been some devices for rehabilitations of upper limb such as electronic device and mechanical device which is well-known as the passive one. These devices make the motion of upper limbs and stimulate the wrist, elbow, shoulder joints with muscles. This motion does by using the patient’s normal hand (left or right hand) and rotating the wounded hand’s wrist to be recovered by the clockwise or counterclockwise with some angles. Electronic devices for upper limb rehabilitation have the advantage that the electronic ones can supply various rehabilitation exercises to the patients. However these electronic devices include relatively expensive components such as various kinds of sensors, controllers, and display device. Therefore, the prices of implementation are too expensive. On the other hand, in conventional passive upper limb rehabilitation, the patients grasp the both handles without any mechanical links. It does not supply proper rehabilitation motion because the normal hand does not supply the rehabilitation motion to hand to be recovered. So to speak, this is not proper to patients with the one hands trouble such as hemiplegic patients, by himself without the aids of any other persons. In this paper, we describe the mechanical device for rehabilitations of wrist and the proposed handles to be attached in this mechanical device. This proposed handles can generate the three angle motion of wrist such as the roll, pitch and yaw. This proposed device has some features that this device can be implemented with lower costs than electronic devices and can be used whatever the wounded hand is right or left by selecting the lever. Further, when the patient has the rehabilitation exercise intent, the patients can easily use the proposed upper limb rehabilitation devices without the aid of the rehabilitation therapist the energy source is the normal hands of the patients.

A major problem in training device design is specifying the appropriate level of fidelity and required instructional features for learning. This research effort was designed to acquire detailed information about tasks and training device fidelity features. The standard method for developing information about task and fidelity relationships has been to conduct research into training methods using varying degrees of fidelity, or to extrapolate from evaluations of training programs based on newly developed training devices. The rotary-wing operations domain was selected as the basis for gathering detailed relationship data. A Training Device Fidelity analysis was conducted on many of the devices at the Army Aviation School at Ft. Rucker. A survey was then developed that crossed the tasks being trained on the AH-64 CWEPT (Cockpit, Weapons, and Emergency Procedures Trainer) and the UH-1 CPT (Cockpit Procedures Trainer) with the device characteristics present on those training devices. The survey was administered to instructors using the training devices. The survey responses were categorized, and the consensus results are being used in developing expert system rules. The conclusion drawn is that adequate data can be collected using surveys to generate experience-based (versus opinion-based or device evaluation-based) rules for determining necessary and sufficient fidelity aspects for training devices. The method can be used in any training domain that requires training devices, where guidance is inferential and opinion-based, and where those devices are costly and/or need to be very effective.

Abstract Optically driven electronic neuromodulation devices are a novel tool in basic research and offer new prospects in medical therapeutic applications. Optimal operation of such devices requires efficient light capture and charge generation, effective electrical communication across the device’s bioelectronic interface, conformal adhesion to the target tissue, and mechanical stability of the device during the lifetime of the implant—all of which can be tuned by spatial structuring of the device. We demonstrate a 3D structured opto-bioelectronic device—an organic electrolytic photocapacitor spatially designed by depositing the active device layers on an inverted micropyramid-shaped substrate. Ultrathin, transparent, and flexible micropyramid-shaped foil was fabricated by chemical vapour deposition of parylene C on silicon moulds containing arrays of inverted micropyramids, followed by a peel-off procedure. The capacitive current delivered by the devices showed a strong dependency on the underlying spatial structure. The device performance was evaluated by numerical modelling. We propose that the developed numerical model can be used as a basis for the design of future functional 3D design of opto-bioelectronic devices and electrodes.

AbstractWe analyze the diagnosis task in the context of adaptive design and redesign of physical devices. We identify three types of diagnosis tasks that differ in the types of information they take as input: the design does not achieve a desired function of the device, the design results in an undesirable behavior, and a specific structural element in the design misbehaves. We describe a model-based approach for solving the diagnosis task in the context of adaptive design and redesign. This approach uses functional models that explicitly represent the device functions and use them to organize teleological and causal knowledge about the device. In particular, we describe a specific kind of functional model called structure—behavior—function (SBF) models in which the causal behaviors of the device are specified in terms of flow of substances through components. We illustrate the use of SBF models with three examples from Kritik2, a knowledge system that designs new devices by retrieving, diagnosing, and adapting old device designs.

This paper describes some aspects of the fabrication and modeling of a GaN device to be employed in a power amplifier covering one WiMAX frequency band. The work has been carried out in the frame of the TARGET's NoE work package WiSELPAS. Details concerning the AlGaN/GaN device technology and the performed linear and nonlinear measurements are provided. Since these new devices require specific nonlinear models, a procedure for selecting an appropriate simplified nonlinear model and for extracting its parameters is discussed and evaluated. The developed nonlinear model has been experimentally tested under linear and nonlinear conditions. The agreement between experimental and model-predicted performance suggests that the described model could be useful in a preliminary power amplifier design.

DNA strand displacement techniques have been used to implement a broad range of information processing devices, from logic gates, to chemical reaction networks, to architectures for universal computation. Strand displacement techniques enable computational devices to be implemented in DNA without the need for additional components, allowing computation to be programmed solely in terms of nucleotide sequences. A major challenge in the design of strand displacement devices has been to enable rapid analysis of high-level designs while also supporting detailed simulations that include known forms of interference. Another challenge has been to design devices capable of sustaining precise reaction kinetics over long periods, without relying on complex experimental equipment to continually replenish depleted species over time. In this paper, we present a programming language for designing DNA strand displacement devices, which supports progressively increasing levels of molecular detail. The language allows device designs to be programmed using a common syntax and then analysed at varying levels of detail, with or without interference, without needing to modify the program. This allows a trade-off to be made between the level of molecular detail and the computational cost of analysis. We use the language to design a buffered architecture for DNA devices, capable of maintaining precise reaction kinetics for a potentially unbounded period. We test the effectiveness of buffered gates to support long-running computation by designing a DNA strand displacement system capable of sustained oscillations.

This paper describes the design of a Series-Connected Device based on a fixed–frequency LLC resonant converter (SCDLLC). Isolation of the dc-dc converter like the LLC resonant converter is used for the stability of the high voltage system such as a solid-state-transformer (SST). The series-connected devices driving method is one of the methods applicable to a high voltage system. When driving series-connected devices, an auxiliary circuit for voltage balancing between series-connected devices is required, which can be simply implemented using a passive element. In this paper, LLC converter design with balancing circuits configured in parallel with a device is provided, and both the simulations and experiments were performed.

Abstract The article is devoted to the improvement of the tiller designed to operate on rocky soils. The elements of the interaction theory between the tiller work tools and the rocks in the soil are presented. Two cases of the machine blade hitting a rock were analyzed. The improved machine design containing safety devices and a digital alarm system that reports the operator on the safety device response is proposed. Safety devices are installed on each machine section, which reduces the area of untilled soil during their response. A contactless sensor is installed above each section, the signal from which is analyzed by a measuring device according to a special algorithm. Rational values for the main parameters of the tiller section fuses are determined and the time of the section blade hit a rock is studied. The improved tiller sample testing of 2020 and 2021 on rocky soils in the mountainous terrain proved the efficiency of the proposed design.

Embedding the security mechanism into the device is the core of self-securing, on purpose to provide the device with the ability of self-defense. Currently, security of portable storage device is commonly depends on the host, which makes the data easy to be attacked or stolen. Researches on self-securing mechanism on portable device are few. In order to improve the safety of those devices, we proposed the prototype design of self-securing portable storage device based on the framework of ARM+Linux. Combined with access control, intrusion detection based on storage and data encryption/decryption, it can protect data availability, integrity and confidentiality effectively. Since we have expanded researches on self-securing mechanism of portable storage devices, this prototype design is promising to be one kind of trend of intelligent storage.

Designing correct, robust DNA devices is difficult because of the many possibilities for unwanted interference between molecules in the system. DNA strand displacement has been proposed as a design paradigm for DNA devices, and the DNA strand displacement (DSD) programming language has been developed as a means of formally programming and analysing these devices to check for unwanted interference. We demonstrate, for the first time, the use of probabilistic verification techniques to analyse the correctness, reliability and performance of DNA devices during the design phase. We use the probabilistic model checker prism , in combination with the DSD language, to design and debug DNA strand displacement components and to investigate their kinetics. We show how our techniques can be used to identify design flaws and to evaluate the merits of contrasting design decisions, even on devices comprising relatively few inputs. We then demonstrate the use of these components to construct a DNA strand displacement device for approximate majority voting. Finally, we discuss some of the challenges and possible directions for applying these methods to more complex designs.

This paper presents a simple method to design wideband Doherty power amplifiers (DPAs) based on the synthesis of a combiner network which can mimic the response of an ideal compensation of the device reactive output equivalent network and exploit the maximum power capabilities of the device. Using the Wolfspeed’s CGH40006 and CG2H40025 GaN HEMT devices, two DPAs were designed and simulated to demonstrate the effectiveness of the proposed approach. In both cases, a 1.4 GHz bandwidth was obtained together with an efficiency higher than 44 and 49% at 6 dB OBO. The saturated output power was higher than 41.2 and 47 dBm over the band, for the DPAs using the CGH40006 and CG2H40025 devices, respectively.

Background: The focus of the medical device industry and regulatory bodies on cyber security parallels that in other industries, primarily on risk assessment and user education as well as the recognition and response to infiltration. However, transparency of the safety of marketed devices is lacking and developers are not embracing optimal design practices with new devices. Achieving cyber safe diabetes devices: To improve understanding of cyber safety by clinicians and patients, and inform decision making on use practices of medical devices requires disclosure by device manufacturers of the results of their cyber security testing. Furthermore, developers should immediately shift their design processes to deliver better cyber safety, exemplified by use of state of the art encryption, secure operating systems, and memory protections from malware.

The need for integrated passive components which meet the stringent power system requirements imposed by increased data rates, signal path density and challenging power distribution network topologies in integrated systems yield diverse motivations for high density, miniaturized capacitors capable of quickly sourcing large quantities of current. These diverse motivations have led to the realization of high density capacitor structures through the means of several technologies. These structures have been evaluated as high-speed, energy storage devices and their respective fabrication technologies have been closely compared for matching integrated circuit speed and density increase, chip current requirements, low resistance, low leakage current, high capacitance and compatibility with relatively high frequencies of operation (~1GHz). These technologies include devices that utilize pn junctions, Schottky barriers, optimized surface area techniques and the utilization of high dielectric constant (high-K) materials, such as hafnium oxide, as a dielectric layer through the means of atomic layer deposition (ALD). The resulting devices were micro-machined, large surface area, thin, high-density capacitor technologies optimized as embedded passive devices for thin silicon interposers. This work outlines the design, fabrication, simulation and testing of each device revision using standard silicon microfabrication processes and silicon interposer technologies. Consequently, capacitive storage devices were micro-machined with geometries which maximize surface area and exhibit the capability of sourcing 100A of current with a response time greater than 100 A/nsec through the use of thin layered, ALD high-K materials. The simulation and testing of these devices show general agreement when subjected to a standard ring-down procedure. This paper provides descriptions and design challenges encountered during fabrication, testing and integration of these passive devices. In addition, potential device integration and implementation strategies for use in silicon interposers are also provided. The modification and revision of several device generations is documented showing increased device capacitance density, maximized current capabilities and minimized effects of series inductance and resistance. The resulting structures are thin, capacitive devices that may be micro-machined using industry standard Si MEMS processes and are compatible with Si interposer 3D technologies. The subsequent design processes allow integrated passive components to be attached beneath chips in order to maximize system area and minimize the chip real estate required for capacitive energy storage devices.

Abstract In this work, we report a paradigmatic shift in bioinspired microchannel heat exchanger design toward its integration into thin film wearable devices, thermally active surfaces in buildings, photovoltaic devices, and other thermoregulating devices whose typical cooling fluxes are below 1 kW m−2. The transparent thermoregulation device is fabricated by bonding a thin corrugated elastomeric film to the surface of a substrate to form a microchannel water-circuit with bioinspired unit cell geometry. Inspired by the dynamic scaling of flow systems in nature, we introduce empirically derived sizing rules and a novel numerical optimization method to maximize the thermoregulation performance of the microchannel network by enhancing the uniformity of flow distribution. The optimized network design results in a 25% to 37% increase in the heat flux compared to non-optimized designs. The study demonstrates the versatility of the presented design and architecture by fabricating and testing a scaled-up numerically optimized heat exchanger device for building-scale and wearable applications.

<span lang="EN-US">The progress of Carbon Nanotube Field Effect Transistor (CNTFET) devices has facilitated the trimness of mobile phones, computers and all other electronic devices. CNTFET devices contribute to model these electronics instruments that require designing the devices. This research consists of the design and verification of the CNTFET device's small signal model. Scattering parameters (S-parameters) is extracted from the CNTFET model to construct equivalent small model circuit. Current sources, capacitors and resistors are involved to evaluate this equivalent circuit. S-parameters and small signal models are elaborated to analyze using a technique to form the small signal equivalent circuit model. In this design modeling process, at first intrinsic device's Y-parameters are determined. After that series of impedances are calculated.

This research aimed to find an efficient method of responding to the various variables that may arise during the process of designing and constructing an immersive exhibition space. A digital twin of the exhibition space was generated, a real-time rendering method was applied using a game engine, and the optical phenomena of several typical devices used in immersive exhibitions were simulated. The functions simulated in this study are applicable to the generated digital twin to predict how the various devices installed in the exhibition space would operate in the actual exhibition. Thereby, the possibility that the simulation results of the core elements that constitute the exhibition content be immediately applied to the operation of the various devices in the exhibition space in real-time could be explored. Not all the devices and functions used in an immersive exhibition were simulated, so the model used in the paper must be modified according to the circumstances of the applications. Through additional research, the method of responding to various installations and devices must be expanded.

This study developed the pre-heating device which heats the water by using the exhaust gases from gas-operated hot-water heater. Thus the temperature of water is raised at an exit of the pre-heating device. The pre-heated water is then transport to the gas-operated hot-water heater to increase the water temperature which is used for showers. Thus, the thermal performance is enhanced with the pre-heating device. The overall performance of the absorption heater system is analyzed by finite element analysis. The different types of pre-heating devices are simulated for the thermal performance. Other important considerations for producing the pre-heating devices are the bending-tube technology and manufacturing cost. The appropriated design of pre-heating device is selected for producing. Thus the performance and testing of pre-heating devices will be carried out.

Pointing sticks and touch pads remain the leading integrated pointing devices incorporated into notebook computers. Manufacturers have implemented dual point designs that include a pointing stick and touch pad on the same system to accommodate polarized preferences for pointing devices among users. Study of dual point designs analyzed the individual devices and identified strengths and weaknesses of combined designs. Findings indicate that with certain system attributes held constant, advanced technologies for pointing stick and touch pad produce near equal performance results and confirm hypotheses from previous research that user device preference and prior learning are key-contributing variables. Different types of pointing stick and touch pad technologies also lead to varying performance and preference results. in addition, users' abilities to transition to an alternate device depend on the device used during prior learning. Data suggests that unless device design is optimized for use of both devices, dual point designs may degrade performance and satisfaction of at least one component device when compared to similar metrics of the same device from single point designs.

Internet of Things (IoT) is a smart infrastructure of the unique identification device capable of wireless communication with each other, and human services on a large scale through the Internet. The IoT devices themselves must self-aware and harvest the energy they need from ambient sources. Simultaneous wireless information and power transfer (SWIPT) is a promising new solution to provide an opportunity for energy-restrained wireless devices to operate uninterruptedly. In this paper, we propose a beamforming approach for Internet of Things (IoT) multi-input multi-output (MIMO) SWIPT downlink systems, which minimizes the mean square error (MSE) of the information decode (ID) device while satisfying the energy constraint of the energy harvesting (EH) device. Simulation results are provided to evaluate the performance and confirm the efficiency of the proposed algorithm.

The current work aimed to study and understand the nature of interaction between aerosol/dusts and its surrounding medium such as air and/or solid dry or wet surfaces. Results were used as benchmarks to design spraying mechanisms and devices that can be used for optimizing the spraying device design geometry and shape with adjustable distance between cup and pin in parts and to lower manufacturing cost using solid works flow simulations software. Different spray devices were designed and evaluated with simulation, from simple ideas to complex device shapes. The simulation focused on studying the air profile and stream lines, with and without particles (dust particles with spherical shape and 5 micro meters in diameters), pressure, velocity and density during spraying process. Simulation results for the last modified spraying device case-6 with mass flow rate of 1.5 kg/s, and distance between cup and pin of ( part 2) 3.3 mm showed excellent mixing and spreading mechanisms with uniform velocity of flow, density and pressure through the whole device. Even the tested device in case-3 with mass flow rate 1 kg/s, distance between cup and pin of (part 2) 6.6 mm was also perfect. This device is expected to be used as a nanoparticle spraying device, a pollination device in date palm tree pollination and an aerosols aerodynamic behavior simulating system

Due to increasing speed, density and number of signal paths in integrated circuits, motivations for high density capacitors capable of quickly sourcing large amounts of current have led to many design and fabrication investigations. This work outlines continued efforts to achieve devices which meet these stringent requirements and are compatible with standard silicon fabrication processes as well as silicon interposer technologies. Previous work has been further developed resulting in devices exhibiting greater capacitance values by employing geometries which maximize surface area. The Atomic Layer Deposition (ALD) of thin layered high K materials, such as Hafnium Oxide, as opposed to previous silicon-dioxide based devices effectively increased the capacitance per unit area of the structures. This paper outlines the design, fabrication, and testing of high density micro-machined embedded capacitors capable of quickly sourcing (i.e. risetimes greater than 100A/nsec) high currents (i.e. greater than 100A). These devices were successfully simulated then tested using a standard ringdown procedure. Generally, the resulting device characterization found during testing stages strongly correlates to the expected simulated device behavior. Subsequent descriptions and design challenges encountered during fabrication, testing and integration of these passive devices are outlined, as well as potential device integration and implementation strategies for use in silicon interposers. The modification and revision of several device generations is documented and presented. Increased device capacitive density, maximized current capabilities and minimized effects of series inductance and resistance are presented. These resulting thin, capacitive structures exhibit compatibility with Si interposer technology.

AbstractAlthough product family design methods are well established, little research has focused on Product-Service-System (PSS) family design. A PSS family design method is proposed in this paper that parallels methodology for designing product families. Separate platforms are proposed for products and for services. However, couplings between product and service platforms are identified and incorporated into the design method. Design problem formulations are proposed for PSS family platforms and for the PSS family itself, using a module-based approach, in contrast to a platform scaling approach. Alternative methods are investigated and compared for solving these problems. The application domain of Assistive Mobility (AM) is identified as a promising PSS family in this work. If smart technologies are integrated into AM devices, such as manual wheelchairs, powered wheelchairs, walkers, and rollators, then patient diagnosis and treatment, as well as device maintenance, services are enabled with these smart technologies, demonstrating that smart AM devices are a promising PSS family.
